A single-pass grid-based algorithm for clustering big data on spatial databases
(Massachusetts Institute of Technology, 2017)
The problem of clustering multi-dimensional data has been well researched in the scientific community. It is a problem with wide scope and applications. With the rapid growth of very large databases, traditional clustering ...
Squadbox : a tool to combat email harassment using friendsourced moderation
(Massachusetts Institute of Technology, 2017)
Online harassment is both a social and technical problem, and has yet to be successfully solved. In order to better understand the issue and the challenges surrounding it, we conducted interviews with eighteen recipients ...
Dynamic, personalized discrete choice incentive allocation to optimize system performance
(Massachusetts Institute of Technology, 2017)
Incentivization is a powerful way to get independent agents to make choices that drive a system to a desired optimum. Simply offering compensation for making a certain choice is enough to change the behavior of some people. ...
Visualizing Trends on Twitter
(Massachusetts Institute of Technology, 2013)
With its popularity, Twitter has become an increasingly valuable source of real-time, user-generated information about interesting events in our world. This thesis presents TwitGeo, a system to explore and visualize trending ...
Decision support tool for dynamic workforce scheduling in manufacturing environments \
(Massachusetts Institute of Technology, 2013)
Scheduling for production in manufacturing environments requires an immense amount of planning. A large number of factors such as part availability, production cost, space constraints and labor supply must be taken into ...
Biologically inspired digital fabrication
(Massachusetts Institute of Technology, 2013)
Objects and systems in nature are models for the practice of sustainable design and fabrication. From trees to bones, natural systems are characterized by the constant interplay of creation, environmental response, and ...
Construction of a quantum gas microscope for fermionic atoms
(Massachusetts Institute of Technology, 2013)
This thesis reports the construction of a novel apparatus for experiments with ultracold atoms in optical lattices: the Fermi gas microscope. Improving upon similar designs for bosonic atoms, our Fermi gas microscope has ...
Low-cost educational stochastic optical reconstruction microscopy (eSTORM)
(Massachusetts Institute of Technology, 2013)
A stochastic optical reconstruction microscope was built and demonstrated for under $20,000, enabling hands-on learning of single-molecule localization concepts in teaching laboratories. This was accomplished by replacing ...
A standalone capacitively coupled occupancy sensor
(Massachusetts Institute of Technology, 2013)
This thesis presents the design and implementation of a standalone, capacitively coupled, occupancy sensor. Unlike previous iterations, the new sensor is decoupled from the fluorescent lamp. A well controlled, high voltage ...
GroverCode : code canonicalization and clustering applied to grading
(Massachusetts Institute of Technology, 2016)
Teachers of MOOCs need to analyze large quantities of student submissions. There are a few systems designed to provide feedback at scale. Adapting these systems for residential courses would provide a substantial benefit ...
